摘 要:针对1302北底抽巷陷落柱高冒区情况,采用设置风障、安装抽放管路和压风管路的方式进行高冒区瓦斯处理,并采用双抬棚超前木梁+注浆填充+工字钢棚+喷浆+二次注浆方式进行高冒区顶板处理。实践证明,巷道围岩变形得到了有效控制,该技术方案安全可靠,具有借鉴应用价值。For the situation of the high risk area of the collapse columns at the 1302 north end pumping roadway, gas treatment in the high risk area was carried out by setting up wind barriers, installing extraction lines and pressure lines, and roof treatment was carried out by applying double lifting shed advanced wood beam + grouting filling + I-steel shed + grouting + secondary grouting for high risk areas. The practice proves that the surrounding rock deformation of the roadway has been effectively controlled. The technology scheme is safe and reliable, and has reference value.
